visitsb/amazonlinuxecs repository overview

⁠What is it?

Amazon Linux provides a stable, secure, and high-performance execution environment for applications. This is an ECS friendly version that allows you to create an ECS service into which you can SSH.

⁠Why?

This helps to have a container acting as a daemon. The primary goal I have in mind is to test out any connectivity issues between your containers, work out any name resolution between services and any other daemon like activities.

⁠How to use?

$ docker run -it -p 22:22 -p 8080:8080 --name amazonlinuxecs visitsb/amazonlinuxecs:latest

Starting SSH daemon...
Starting GOSS health checks...
Going to sleep for 60 seconds. Zzz...

Now you can ssh into the the container using the exposed port 22, user ec2-user using the private key displayed when you start the container.

Note: PubkeyAuthentication is setup by default. The public/private key contents are displayed when you start the container. Password based login is enabled too (Default password ec2-user).

$ /usr/bin/ssh [email protected] 22 
The authenticity of host '127.0.0.1 (127.0.0.1)' can't be established.
ECDSA key fingerprint is SHA256:AAo6G8MtS/3FqMQ7TW1WtoLe2bffQiuvpXblBhi1elE.
Are you sure you want to continue connecting (yes/no)? yes

⁠Amazon ECS setup

Setup a Network Load Balancer⁠ to serve a TCP port 22 backed by a TCP Listener⁠ forwarding traffic to your Target Group⁠.

⁠Health checks

The health checks are exposed on using HTTP on port 8080 under path /healthz. This is useful to setup your ECS container as a target group's health check under Network Load Balancer⁠.
